Metrics elasticsearch successful requests

Question

Is it possible to have some metrics about how many search requests were processed over a certain time on ElasticSearch at AWS? Something like the cloudwatch monitoring for Cloudsearch that you can check the number of successful requests per minute (RPM):

Answer 1

Just find out the endpoint _stats that allow user to retrieve interesting metrics, so basically you will have to divide indices.search.query_total for indices.search.query_time_in_millis to have an average time for each query.

Still don't know a good way to have a real time data to plot a monitoring graph
